MIKE SMITH and MICHAEL CAST As fire continued to burn in the iconic M&M Cigar Store in Butte Friday afternoon, firefighters detached the sign so it could be moved with a crane. MEAGAN THOMPSON Firefighters say an early-morning fire that gutted the iconic M&M Cigar Store in Uptown Butte Friday likely started in the stove area, and before long, flames were shooting though the ventilation system. Workers closed the M&M and left at 12:30 a.m. and firefighters were called at 3 a.m., said Butte-Silver Bow Fire Marshal Zach Osborne. Two firefighters got inside quickly to find flames coming from the hood system above the stove and grill.
